Small and strange problem

[Graham Samuel]

I set this hare running initially. I really do think there is a bug, because the thing works when stepped through but not if it’s allowed to run without interruption. In the stepped-through activity it’s easy to see that tMins does have a value. In my example it’s 31, or maybe it’s a string of which the visible part is “31”. But the fact remains the script behaves in two different ways, at least on my computer.

As I tiny bit of background, the script tries to parse a string that represents a longitude, copied from a web site. It certainly has some weird characters in it, but I thought I’d got round then. FWIW, the string is 

004° 31′ 50″ W

I am going to report it to the mother ship
